T3M Series NCC National Controls Delay on Break Time Delay Relay. (50 ms to over 16 Hours)
The T3M Series is a Delay On Break time delay relay featuring easy to program multiple time ranges and digital time selection. Voltage is continuously applied to the timer. Depending on the model, either a switch closure or application of control voltage causes the relay coil to be energized and remain so as long as the switch is held closed or control voltage is applied. Opening the switch or removing the control voltage starts the timing cycle. At the end of the preset time delay, the relay coil de-energizes and the timer is ready for a new timing cycle.
